Answer:
The scale factor is 4.5
Step-by-step explanation:
Scale factor from ∆RST to ∆XYZ = side length of ∆XYZ / corresponding side length of ∆RST
Thus:
XY corresponds to RS
XY = 45
RS = 10
Therefore:
Scale factor = 45/10 = 4.5
Scale factor from ∆RST to ∆XYZ = 4.5
Answer:
Z = (42-20)/4 = 5.5
Z = X-μ / σ
Step-by-step explanation:
Hello!
The formula for finding area of a rectangle is length × width
<em><u>1st garden
</u></em>l = 10.25
<u><em /></u><em />w = 6.2
6.2 × 10.25 = 63.55
Area = 63.55 ft²
<em><u>2nd garden</u></em>
l = 20.5
w = 12.4
20.5 × 12.4 = 254.2
Area = 254.2 ft²
Divide the bigger area by the smaller area
254.2 ÷ 63.55 = 4
Answer:
PR = 20
Step-by-step explanation:
The perimeter is the sum of the 3 sides, thus
4z + z + 3 + 3z + 2 = 45 ← simplify left side
8z + 5 = 45 ( subtract 5 from both sides )
8z = 40 ( divide both sides by 8 )
z = 5
PR = 4z = 4 × 5 = 20
